Engineering Bricks

Engineering bricks are specialised bricks chosen for their functional qualities rather than their aesthetic appeal. They are particularly valued for their strength, reduced water absorption capabilities, and resistance to acidic conditions. These bricks are primarily selected based on these technical characteristics rather than their visual aspects.

Typically, engineering bricks find their use in various construction projects where durability and resistance to environmental factors such as frost and moisture are crucial. Common applications include subterranean structures like manholes and sewers, as well as ground works, retaining walls, and for damp-proofing measures. Despite being quite prevalent, these bricks lack the wide range of styles found in standard facing bricks due to their focus on functionality over appearance.

These bricks are categorised into two classes based on their strength and water absorption properties:

• Class A engineering bricks are recognised for their superior strength (exceeding 125N/mm² in compressive strength) and minimal water absorption (less than 4.5%).
• Class B bricks, while still strong (with a compressive strength exceeding 75N/mm²), are more commonly used and have a slightly higher water absorption rate (less than 7%).

In terms of colour choices, engineering bricks are available in a spectrum of colours including red, white, tan, brown, orange, grey, and black. These bricks come in a range of styles and cuts, offering some degree of choice within their functional constraints.

Major brick manufacturers like Fonterra, LBC, Wienerberger, London Bricks, and Ibstock, amongst others, provide these engineering bricks. 

Advantages of Using Engineering Bricks:

• Load Bearing: Their remarkable compressive strength makes them suitable for structures that need to support heavy loads.
• Damp Environments: Excelling in water resistance, these bricks are perfect for areas prone to moisture.
• Retaining Walls: Their durability makes them a preferred choice for building strong retaining walls.
• Groundworks: Often used in below-ground applications, they provide a reliable, moisture-resistant foundation.
• Decorative Purposes: Beyond their functional attributes, the unique texture and appearance of engineering bricks can also be leveraged for aesthetic enhancements in design-focused projects.
